The Christian McCaffrey era with the San Francisco 49ers is off to quite a promising start.

After tallying 62 yards from scrimmage in his 49ers debut against the Kansas City Chiefs last week, McCaffrey made a strong first impression in his first career clash against the Los Angeles Rams donning a San Francisco jersey.

In need of a score after Rams quarterback Matthew Stafford anchored an 88-yard touchdown drive, the 49ers opted to go deep into their playbook to catch the reigning Super Bowl champions off guard.

On a crucial second down play in the early stages of the second quarter, McCaffrey received the football out on the right side of the field and instead of taking off with the ball, he wound up connecting with Brandon Aiyuk for a 34-yard touchdown. Rams defensive back Troy Hill was well under the impression that McCaffrey was going to run with the ball, while free safety Nick Scott failed to catch up to the speedy Aiyuk.

Twitter loved this trick play that the 49ers elected to call for McCaffrey, as the versatile running back scored his first touchdown with the NFC West powerhouse.
